install issues on Solaris

hi there, some of you may remember my post from yesterday ( titled install to unix ... hastles ) as I said in that one I was using Solaris 9 ( the newest ver of the Solaris OS ) i have since gone back to Solaris 8 and am having the same problem when I go to do the "make" looking through the ./configure output i discovered it can find "unix.h" but when I do the make (and inparticular when it goes through the Zend Makefile ) it cannot find it.. any one got any clues or suggestions? ( Solaris does come with an old ver (4.0.6 I think) on a companion CD but I wanna try and figure this one out as it's a newer ver of php (4.2.1) ) any help would be apreciated... I can attach soft copies of both the make and the configure screen outputs for any that are interested... Cheers Peter "the only dumb question is the one that wasn't asked"
